Question

If a bank clerk is fixed in the salary 3200-85-4900, when will he achieve his maximum?

Answer 1

Answer: 21st year of service

Step-by-step explanation:

3200 - 85 -4900

given that the starting salary is 3200 and ending salary as 4900 (fixed) with an increment of rs 85

here, a=3200     an=4900   and common difference d= 85

an = a+ (n-1) d

4900 = 3200 + (n-1)85

4900-3200 = 85n-85

1700 = 85n-85

1700+85 =85n

1785=85n

n=1785/85

n=21

the clerk will achieve his maximum salary in his 21st year of service
